Abstract: A method for assisting in locating a target object, a method for locating a target object, and an apparatus. In an embodiment, the method for assisting in locating a target object is applied to a station (STA), and the method includes: receiving a wireless sensing sounding frame including radar measurement indication information from an access point (AP); sending an uplink data packet to the AP, recording a first sending moment, and performing radar measurement on a target object based on the radar measurement indication information to obtain a radar measurement result; receiving a downlink data packet from the AP, and recording a first receiving moment; and sending the first sending moment, the first receiving moment and the radar measurement result to the AP.

Abstract: This provides a spatial multiplexing method and apparatus, to introduce WLAN sensing into a conventional spatial multiplexing mechanism and improve communication efficiency. The method includes: An AP sends a first request message to a first station and a second station, to request to measure channel quality in one or more sensing beam directions in a first SP; the AP sends a second request message to a third station and a fourth station, to request to measure channel quality in a communications beam direction in a second SP; the first station, the second station, the third station, and the fourth station separately perform measurement and report respective first measurement results; and the AP receives the first measurement results of the stations, and determines, based on the first measurement results, whether to perform spatial multiplexing on the first SP and the second SP.
